摘要
Abstract
1-Methyl-3,4-dinitropyrazole(MDNP)was synthesized via methylation using 3,4-dinitropyrazole(DNP) as starting material.The structure of the target product was characterized by melting point determination,IR spectrometry and nuclear magnetic resonance etc.The single crystal of MDNP is cultured at room temperature and its structure was determined by a four-circle X-ray diffractometer.The thermal performance of MDNP was studied by DSC.The detonation velocity and detonation pressure of MDNP were calculated by Kamlet formula.Results show that the crystal is monoclinic,space group P 21/n with cell parameters of a =0.7263 nm,b =1.514 3 nm,c =1.0368 nm,V = 1.123 4 nm3 ,Z = 4,D = 1.480 g/cm3 ,F (0 0 0 )= 520.MDNP has good thermal stability.The detonation velocity and detonation pressure are 6.14km/s and 17.0GPa,respectively.It is an energetic material with potential application value.关键词
